Patents by Inventor Todd Jeffrey Hewitt

Todd Jeffrey Hewitt has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 9289215
    Abstract: This invention is directed to implantable coils and, more particularly, to a coil implant having a stretch-resistant member internal to the coil. The implant of the invention is able to freely articulate and torque prior to delivery. Once delivered, the implant is no longer stretch resistant and is therefore able to substantially conform to the vascular site.

  • Patent number: 8974409
    Abstract: A catheter used for treatment of complex vasculature, such as a bifurcated aneurysm, is provided with an inflatable balloon at a distal portion thereof. The shape, location and material of the inflatable balloon are selected such that when inflated, the balloon conforms to the shape of the complex vasculature, or at least a portion thereof, without appreciably deforming the vessel walls. In this manner, the balloon can be used to control flow in the vasculature, for example occluding a selected branch of the vasculature during introduction of material in order concentrate the material and minimize its disbursement by blood flow.

  • Patent number: 8864790
    Abstract: An intravascular implant delivery system carries an implant by retaining an engagement member engaging the implant in a position proximal of an aperture at a distal end of the delivery system. The engagement member is retained proximal to the aperture by a cord that obstructs the movement of the engagement member through the aperture. The engagement member is free to rotate and move within an area defined by the delivery system, allowing the implant to react to forces imparted to the implant by the movement of the delivery system and implant through a delivery catheter. Once the implant is in a desired implant position, the cord is moved away from an aperture and the engagement member is allowed to move away from the delivery system.

  • Patent number: 8801747
    Abstract: This invention is directed to an implant having a coil for embolizing a vascular site, such as aneurysm. The coil has a specific three-dimensional shape that is achieved by winding the coil around a mandrel in a specific pattern and then heat setting the coil and the mandrel, another aspect of the invention. The three-dimensional shape resembles unclosed mobius loops. Also provided are methods of making the coil and methods of embolizing vascular site.
